By GlobalDataRaytheon’s LTAMDS radar, part of the US Army’s Integrated Air and Missile Defense system, is designed to counter advanced threats, including hypersonic weapons.
It also supports existing investments in the Patriot system.
LTAMDS transitioned into the production phase after completing the US Army’s flight test programme in April 2025. It is designated as a US Army programme of record.
By August 2025, RTX successfully demonstrated the radar’s 360-degree sensing capabilities through a flight test. A live-fire demonstration showcasing these capabilities was conducted in November of last year.
Raytheon has supplied the US Army with the first six LTAMDS under a contract awarded in 2019. The company is producing eight additional LTAMDS radars each year and plans to increase its output to 12 units annually to address international requirements.
Poland has become the initial foreign operator to include LTAMDS in its air and missile defence system.
Raytheon Missiles and Defense secured a contract valued at $2.1bn in August 2024 from the US Department of Defense to produce the LTAMDS for both the US and Poland.
